> AvroDeserializer incorrectly assumes keys to Maps will always be of type
> 'org.apache.avro.util.Utf8'
> ----------------------------------------------------------------------------------------------------
>
> Key: HIVE-5865
> URL: https://issues.apache.org/jira/browse/HIVE-5865
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.11.0, 0.12.0, 0.13.0
> Reporter: Ben Roling
> Attachments: HIVE-5865-v2.patch, HIVE-5865.2.patch,

> AvroDeserializer. deserializeMap() incorrectly assumes the type of they keys
> will always be 'org.apache.avro.util.Utf8'. If the reader schema defines
> "avro.java.string"="String", this assumption does not hold, resulting in a
> ClassCastException.
> I think a simple fix would be to define 'mapDatum' with type
> Map<CharSequence,Object> instead of Map<Utf8,Object>. Assuming the key has
> the more general type of 'CharSequence' avoids the need to make an assumption
> of either String or Utf8.
> I discovered the issue when using Hive 0.11.0. Looking at the tags it is
> also there is in 0.12.0 and trunk:
> https://github.com/apache/hive/blob/99f5bfcdf64330d062a30c0c9d83be1fbee54c34/serde/src/java/org/apache/hadoop/hive/serde2/avro/AvroDeserializer.java#L313
> The reason I saw this issue was because I pointed my Hive table to a schema
> file I populated based on pulling the schema from the SCHEMA$ attribute of an
> Avro generated Java class and I used stringType=String in the configuration
> of the avro-maven-plugin when generating my Java classes.
> If I alter the schema my Hive table points to such that it doesn't have the
> "avro.java.string" attribute on my "map" type objects then queries work fine
> but if I leave those in there I get the ClassCastException anytime I try to
> query the table.
